 Let's start with the Torbutton changes here:

 2a501682217eff74df47f45c60618b71f2a38353 -- please add the dependent
 changes to other files to this commit as well so it is self-contained as
 much as possible (there are still mentions of `torcookiedialog.xul`,
 `popup.xul` etc. in other files)

 18e7226776301a82bb2c5715739b25f9c2b281ad -- There are several things to
 fix up/think through, in no particular order:

 1) What is the reason for commenting out code in the patch? If we don't
 need it then we should remove it. Additionally, the `torbutton-new-
 identity` part is even disabled only sometimes but it's not obvious why
 not every time.

 2) In `torbutton_utils.js` there is `Services` used, but `// let {
 Services }`

 3) In aboutTor.js (and `cookie-jar-selector.js` + `domain-isolator.js` +
 `dragDropFilter.js` + `external-app-blocker.js` + `torCheckService.js` +
 `torbutton-logger.js` + partly `tor-control-port.js` + `utils.js`)
 we have
 {{{
 const {XPCOMUtils}
 const {Services}
 }}}
 while having spaces after and before the curly braces elsewhere in the
 same changes, please stick to one style.

 4) nsIObserverService in cookie-jar-selector.js -> Services.obs

 5) `+  QueryInterface: ChromeUtils.generateQI([Ci.nsISupports,
 Ci.nsIClassInfo]),`

 Why suddenly here `Ci.nsISupports` but a lot of other `generateQI()` calls
 don't have it? There is more of this in other components, like `domain-
 isolator.js`, `dragDropFilter.js`, `external-app-blocker.js`,
 `torCheckService.js`, `torbutton-logger.js`

 6) s/mecanism/mechanism/ in `noscript-control.js`

 7) Why do we need to resort to `broadCastAsyncMessage` and
 `sendAsyncMessage` would not be enough?

 8) There is an `addTab` call in `menu-overlay.xul` that needs to get
 adjusted

 9)
 {{{
             eventSuppressor = browser.contentWindow.
                 QueryInterface(Ci.nsIInterfaceRequestor).
                        getInterface(Ci.nsIDOMWindowUtils);
 }}}
 We should use `windowUtils` here as well, no? Not sure whether we can just
 take `m_tb_domWindowUtils` or actually need the content window version,
 though.

 8) It seems you missed to adapt `startup-observer.js` and doing all the
 clean-up there, too?

 9) In `aboutTor-content.js` replace
 {{{
 let brandBundle = Cc["@mozilla.org/intl/stringbundle;1"]
                           .getService(Ci.nsIStringBundleService)
 }}}
 with `Services.strings`?

 10) `new Array()` in `let tabsToRemove = new Array();` in torbutton.js
 should get changed as well.

 11) There are `nsICookieManager2` calls in `cookie-jar-selector.js` which
 could get replaced by `Services.cookies`.

 Marking this as `needs_revision` while I look over the other commits.
